IMPROVEMENT IN HARRows.

Specification forming part of Letters Patent No. 166,061, dated July Q7,1875; application filed February 1, 1875.

To all whom 'it may concern:

Be it known that I, JOHN S. BEAZELL, of

Chillicothe, Missouri, have made and invented a new and usefulImprovement in Harrows, of which the following is a specification:

My invention relates to improvements in harrows. It consists of tworevolving harrowframes, each having a post provided with a straightdiameter, extending from its base to about the center of its length, anda tapering'diameter for a short distance above the straight diameter,forming a seat for the washer M, in combination with a forked shoehaving an upper and a lower eye,`and a connecting-bar, provided withbearings having eyes corresponding with the straight diameter of thepost, as will hereinafter more fully appear.

The posts are secured to the centers of the frames, and are tapered neartheir upper extremities, but not at their bases; and conformed to turnupon them are forked shoes, that are attached to the ends of draftbars,a washer being provided to fit upon the upper portion of the taperedpart of the post, to remove the friction of the coupling and drag barsfrom the foot-plate B, by sustaining the upper portion of the forkedshoes D. The apertures in the forked shoes are of unequal size, adaptedto the upper and lower parts of the post.

A coupling-bar, provided with a hand-piece, is arranged with a metallicbearing at each end, which is passed over the posts between the bearingsof the forkedjshoe.

The draft-bars are connected at their forward extremities by acoupling-bar, which is so adjusted as to throw the lines of power between the two posts, thus compelling the frames to move outward.

In the accompanying drawings, Figure l is a perspective view of a deviceembodying the invention. Fig.` 2 is a detached view of one ofthe posts;Fig. 3, a like view of one of the forked shoes,-and Fig. 4 asimilar viewof one -of the bearings upon the ends of the couplingbar.

A are the frames, which are of any suitable form and construction,provided with the teeth ct, which are preferably round. At their centersare secured the metallic foot-plates B,

to lwhich the posts C are attached; or the posts the forked shoes D,their forward ends being connected by the coupling-bar H, which isaujusted by the pin L and apertures i. K is the rear coupling-bar,having a hand-piece, which is provided at both ends with the bearings L,having the rectangular shoulders m, the exact form of which appears inFig. 4C. The bearings L are conformed with relation to the posts C andthe bearings of the forked shoes D, so

that they may be inserted to occupy the position shown in Fig. 1, andsecured by the pins 0, the several parts being arranged to fully effecttheir objects, and at the same time permit a free rotation of the framesA. The.

metallic washers M fit upon the upper part of the tapered portion of thepost c, and serve to sustain the forked shoes, so that the portion ofthe shoes, as well as the journal of the rear coupling-bar K, canrevolve upon the post without any friction between their upper and lowersurfaces, or with the foot-plate B, the entire horizontal friction beingupon the upper surface of the washer M, the object being to afford playfor the frames in passing over dangerous ground, to effect which thewashers and bearings are arranged with the requisite intervals or spacesbetween them.

The connection of the ends of the draft-bars E with the coupling-bar His such that they incline toward each other, whereby the frames aremoved outward to left and right, thus freeing themselves at eachrevolution. To this end the length of the bar K is such that they willbe held in suitable proximity to each other.

The operation of the device will be readily understood, and convenientmeans of practicing the invention will suggest themselves withoutfurther description of the details.

What I claim 'as my invention.y and desire Witnessmy'ha-ndthSBOthdaJy-of January,

to secure by Let-ters Pfl-tent, is A. D. 1875.
